BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to a DIY frame for picture or poster, andmore to particularly to a frame kit for supporting and displaying alarge-scale sheet-like object such as a poster or a picture.

2. Description of Related Arts

Posters or pictures are widely used in the marketing materials forpromoting a business. For example, a poster or a picture may be used ina store for attracting customers. A poster or a picture may also berequired for use in an exhibition or a trade-show. However, conventionalmethod of mounting or supporting a picture or poster involves a largescale poster or picture frame which is very expensive in nature. After apicture or poster is mounted onto a frame, the frame is then supportedby a support stand for supporting onto a ground surface. Because of thesize of the poster or the picture is usually very large, the weight ofthe frame and the support stand are proportional to the size of thepicture or the poster and the cost of providing a frame is very high.

In particular, a regular frame generally includes four side units whichperipherally enclose the poster or the picture, a front transparentcover and a back support board unit. The poster or the picture issandwiched by the front transparent cover and the back support boardunit while the front transparent cover and the back support board unitare connected to the four side units and secure into position through agroove like structure provided on the side units. Accordingly, the frameand the poster or the picture of a particular size have to be perfectlymatched with each other. In other words, the regular frame is requiredto be customized for a picture of a particular size, which is costineffectively and time consuming.

Poster or Picture printing becomes more and more common andself-servicing printing services are also available. The advancedtechnological development in digital camera and computer has alsofacilitated the act of taking picture or poster design by lay person.While the cost of taking picture or poster design and the cost ofprinting are lowered, which is especially important to small to mediumsized businesses, the cost of showing and displaying a poster or pictureremains at a high level because of the high cost of picture or posterframe.

In addition, because the dimension of a particular picture frame isfixed, the picture frame cannot be used for other picture of differentdimension. When the poster or the picture is used for marketing purposein an exhibition or a trade show, it is highly likely that the samepicture or poster will not be used repeatedly and it is also highlylikely that the dimension requirement of the picture frame may be variedto fit the exhibition area or the display area. Therefore, theparticular picture frame which is fit for use for a first occasion maynot be fit for use for a second occasion. This type of picture frame,which does not provide any size flexibilities, is not only environmentalunfriendly, but also cost ineffectively.

Furthermore, because the dimension of a particular frame is fixed, it isnot convenience for storage for future use or for transportation orcarriage. For example, after the particular frame is used in anexhibition or a trade show, the frame can neither be disassembled fortransportation, nor packed into a compact size for storage.

SUMMARY OF THE PRESENT INVENTION

The frame includes aframe arrangement 10 arranged for forming a frame structure and apositioning arrangement 30 arranged for positioning a sheet-like objectonto the frame structure.

Referring to FIGS. 1 to 3 of the drawings, the frame arrangement 10comprises a plurality of frame units 11 connecting together to form theframe structure and a coupling connector 12 for connecting twoadjacently positioned frame units 11. Preferably, the frame units 11 aredetachably connecting together through the coupling connectors 12 suchthat the frame units 11 can be disassembled conveniently.

As shown in FIGS. 2 and 3 of the drawings, the frame arrangement 10includes four frame units 11 providing four sides of the frame structurein which the four frame units 11 are connected by the couplingconnectors 12 at four corners to form a rectangular frame structure. Itis worth mentioning that the number of frame units 11 may be varied toform different frame structure such as a triangular frame structure, ahexagonal frame structure and etc.

In particular, the frame unit 11 has a frame unit body 110 having anelongated construction defining a front side 111, a rear side 112, awidth W from the front side 111 to the rear side 112, a first end 113, asecond end 114 and a length L from the first end 113 to the second end114. The coupling connectors 12 are provided at the first end 113 andthe second end 114 of the frame unit body 110 respectively. Thesheet-like object is arranged to be positioned through the rear side 112of the frame unit body 110 of the frame unit 11. Through providing frameunits 11 of different length L, a frame structure of different size anddimension can be formed. In other words, a user is capable of buying mixand match frame units 11 to make a DIY frame.
